Dr Caplan is the author of some really great essays. But it is true that on this a few other issues he seems to be less that at his peak. This in fact is one of the reasons I stopped looking at that blog that he contributes to.
That author of the essay in "The Economist" writes
"Workers in rich countries earn more than those in poor countries partly because they are better educated but mostly because they live in societies that have, over many years, developed institutions that foster prosperity and peace. It is very hard to transfer Canadian institutions to Cambodia, but quite straightforward for a Cambodian family to fly to Canada. "
If you would do that enough, all you will get is another Cambodia.
